Specification of Letters Patent.

Patented June 8, 1926 Application filed January 30, 1919. Serial No.274,000.

, in Letters Patent of the United States, as

per linotype machinery, No. 436,532, dated Sept. 16, 1890.

In machines manufactured under the above specified patent, theassembling block is, after being filled with the-matrices and spacebands to the extent of a predetermined length of line, elevated by thehand of the typographer by means of alever or key. The object of thisinvention isato relieve the typographer, by means of anelectr0-mechanical mechanism, of this labor.

In the drawing, said drawing forming a part of this specification, thisinvention is illustrated in one embodiment which the electro-mechanicalmechanism may assume, showing its relation and connection to theadjacent parts of the composing machine to which it is applied; theparts of said ma.- chine being designated by plain and exponentiatedletters; while the parts of this in vention are denominated by numerals,similar parts being designatedby similar numerals throughout thedifferent figures of the drawing. 4

Figure 1 illustrates a front elevation of a s'uflicient portion of theoriginal machine, to

our invention and its rela carry and show tion to the adjacent partsof'said machine; Fig. 2 illustrates in detail the position of thecontact points. Fig. 3 is a dia-metrical, lon- "tudinal view on line Ali-AA of Fig. 2; g. e is an end view on line B -Bl O1 'ihis invention,being applied as per Fig, l, operates in the following way Sis theassembling block I fills with the matrices and space bands, theresistant J is urged to the left step by step a distance conforming tothe adjusted space between the contact-point 2 0f the sliding-bar jsadjusting screw 2 and the contact-point 1 of the sliding bar bracketpall 1; said adjusted space being equal to and predetermining the lengthof line set out or composed or the Fig. r to number of matrices andspace-bands assembled in I.

When the desired length of line is thus attained, the electric circuitis closed by means of the above referred to 1 and 2 coming in contactwith each other.

The electric circuit being thus closed, the electro-magnet 6 6- isenergized and, being granted horizontal movement, by means of theleaf-spring 7, to the right, magnetically attaches itself to thecontinuously driven disk 8.

The instant magnetic attachment is effected between 6 and 8, the entiremechanism, as illustrated in detail by Fig. 2, revolves through an arcof suflicient length to elevate by means of'the crank 19 the pitman 20.2O communicating with I, thus elevates I to the stationary guide blockll/L The instant I attains the position of dis charge at M, isautomatically released, from the position to which it has been pressedto the left by the matrices and space bands that were assembled in I,and when so released is pulled to the right by means of'a spring acting.t irough the lever J And should the provision in the original machine,or modification of the original ma chine, fail to instantly release j,when l attains the discharge position at M, and thereby fail to open theelectric circuit at l and 2, a secondary provision is provided in theform of a crank 24 attached to the hub of 19; and adjustable to thedesired position 'or angle by means ofthe set-screw so as to raise oropen the switch :23 at the desired instant.

The electric circuit being instantly opened when I attains the dischargeposition, 6 6 is released from magnetic attachment from 8 and the-weight of l and appurtenances thereof descending, preparatory to beingrefilled, cause the mechanism illustrated in reverse through the arethrough which it revolved. to elevate l, and these movements beingrepeated at intermediate intervals automatically, the main object ofthis invention is accomplished.

The electrical wiring of this invention is arrangedsc that the elevatingmechanism maybe operated by the hand or the foot. of the typographer,when automatic operation is not desired.

That the shock resulting from the magnetic attachment of 6-6 to 8 beeliminated,

10 and 14 are set screws, 16 is a washer and 15 a sleeve. 10, 14:, 15and 16 permit horizontal adjustment on 11 of the driven mechanism 8 and9 relative to coordinate position of the driving mechanism a of theoriginal machine.

()ne embodiment of this invention being as herein illustrated, we wouldhave it understood that modifications thereof embracing similarelectro-mechanical principles as those herein described and illustrated,be contemplated as coming within the scope of claims appended hereunto.

We claim 1. In a typographical machine, an assemblyelevator adapted toreceive a series of matrices, a resistant yielding before said matrices,and means acting to raise said elevator when said resistant has yieldedin .a

eaaeae predetermined amount before said matrices, substantially asSpecified.

2. In a device for automatically raising an assembly elevator, a fixedcontact point, a

and adapted when energizedto'secure it to said rotating disk, meansoperated by said rock shaft to'raise said elevator, an electric circuitacting to energize said magnets when closed, and means acting to closesaid circuit when said elevator contains a series of matrices of apredetermined length, substantially as described.
